            Bug ID: 32296
           Summary: Missing diagnostic for "-(1<<31)"
           Product: clang
           Version: unspecified
          Hardware: PC
                OS: Windows NT
            Status: NEW
          Severity: enhancement
          Priority: P
         Component: -New Bugs
          Assignee: unassignedclangbugs at nondot.org
          Reporter: efriedma at codeaurora.org
                CC: llvm-bugs at lists.llvm.org

Testcase:

int a = -(1<<31);

This is UB; we should warn by default.  (clang does warn for "0-(1<<31)".)
